INSULATOR SUPPORT.

Application filed July 2, 1927.

bur invention relates to improvements in insulator supports, and has tor primary object a support for carrying insulators designed for supporting telegraph, telephone and other electrical wires, and which is capable of being; easily pplied to a brick or stone wall. 7

A. further object is the construction of an insulator support for carryino' an insulator so that toe longitudinal axis or the insulator may be arranged to occupy various positions to the wall to which it applied and so that the grooves of the insulator in which the conductors are located may be arranged to occupy various positions and, he conducting wires may be applied to the insulator in a plane substantially in line with the longitu dinal axis of the conductor so that the con-duc tor wires will not be marred or cut by the walls of the grooves.

In the drawings Fig. 1 is a .traginental section of a brick wall including a portionota joint or seam illustrating the application oi ourinsulator support in the horizontal seam or joint of the wall with an insulator mounted thereon, and its axis extending in a vertical direction;

Fig. 2 is a similar view with the support a joint of a wall illustrating the insulator so that its'lon eitudinal a) 's is arranged at an angle less than a right a 'le to the taceoit "he wall;

Fig. El is a similar view showing our insu later support arranged in the vertical seam or I joint of a wall with the insulator pro ectn a,

downi'vardly om the wall and having its arranged LO the taco of the wall an angle less than a right angle;

4 is a similar view show our insulator in a horizontal the insulator located in a horizontal and its axis extending angle to tical face of the wall; and

Fig. 5 is perspective view the support with the insulator removed.

Referring to the drawings, our i support is preferably tori d of sheet metal and consists oi a head po 1 7 in which is formed an ope no 8 tor the in bolt 9 for secu .i g the insulate port. Theheadpo onTi's Extension 10, which is tol ll so as to term spring tongu The tongue when terms.

the extension 10 so that it can spring downwardly. When the insulator is driven into the joint or seam of a wall, the tongue 12 will accupy substantially the posit-ion as illustrated in Fig. 1, that is to say, its tree end will impinge against the top surface of the extension 10 and the bend. 13 will be some- What'flattened out. As the tongue is formed of resilient and elastic material, when it is driven into position as illustrated in Fig. 1, it will securely hold the insulator support in position.

Formed integral with the head 7 is an angular extension 14 which extends substantially at right angles to the head and in which there is formed an opening 15 for receiving a bolt to secure the insulator. Between the extension 14 and the extension 10 is a shoulder 16, which limits the extent to which the insulator may be driven in the joint or seam and also acts as a brace for the insulator sup port.

It will be noted that the extension 10 of the head 7 extends in a dilterentdirection from the extension 14 and the insulator may be secured by means of the bolt 9 to the head 7101? the insulator or it may be secured by means of a bolt to the extension 14.

When the insulator is secured to the support as illustrated in Fig. 1, it is to be understood that the insulator is supported in a vertical position so as to receive conductor wires leading to it in a horizontal direction. When the insulator is secured to the extension 14 and the support is secured in the vertical seam or joint of a. wall as illustrated in Fig. 2, it will be noticed that the insulator is arranged to receive conducting wires extending upwardly in an angular direction, and when the support is located in the vertical seam of a wall and the insulator extends downwardly, it is adapted to receive conductors extending downwardly in an angular direction as illustrated in Fig. When the support is positioned in the horizontal seam or joint of a wall and the insulator is connected to the extension 14, it is arranged to receive conductors leading in a horizontal direction at an angle to the taco of a building as illustrated F v in 1 1g. 4.

lar in )lan view and that one corn r the not l i i 1 is bent at an angle to the plane e neau portion so that this bent portion will bent at an angle, either a right angle or any other angle, to the plane of the head.

The extension is on the same ]')l11ll3 as head portion 7 while the tongue, whit? :t'ornied integral therewith, extends tudinally t the portion 10 and town head, the free end of this tongue howevbeing spaced sutli s lently above the po: oion if; so that it can move downward without binding on the portion 10, it being un course, that our device consti uct sprin metal so that various portions will be resilient or springy.

An. important feature of our d i it is "formed of a single piece ot nzclal has an inherent spring quality so that any o the gripping portions will act without the necessity of any additional treatment to render then'i resilient or springy.

Having fully described our invention, what we claim is 1. An insulator support formed of a sinpiece of metal, said support being provider. with a head portion, a forward extension bent over on itself, the bent over portion being provided with a bend, a shoulder torn'ied on the head and, arranged in proximity to and parallel with the free end of the bent over portion, a triangular extension bent substair tially at a right angle to the head, said extension being arranged at an angle less than a right angle to the longitudinal axis of the first mentioned extension and the bent over portion.

2. An insulator support formed or a single piece of metal and composed of a head portion provided with an opening and with an integral narrow extension, a resilient tongue formed integral with said extension and ha ing its free end extending towards the bead, an angular extension formed integral with the head portion, and bent at right angles thereto, the line of the bend being arr: gcd diagonally to the longitudinal axis of the forward extension and. tongue, whereby upon the positioning of the support and its arcoinpanying .lator either in the horizontal or vertical seani oi a wall the grooves of the insulator may be positioned to receive conducting wires leading or extending from rnrious lii ctions.

3. An insulator support formed of a single piece of spring metal and composed of a head portion rectangular in plan and having one its corner portions bent diagonally and at an to the plane of the head, said head portion and corner portion each being provided with a bolt receiving opening, and a '5" led tongue portion, said tongue portion being narrower than the head portion and integral with aid head portion.

l. fin insulator support formed of a single p ece of spring metal and composed oi a head portion, rectangular in plan and havirgone 0 its corner portions bent diagonally and at right angles to the plane of the hezuh said head portion and corner portion each being provided with a bolt rceeiviiig opening, and a resilient folded tongue portion integral with and of less width than said head zortion.

In testimony whereof we have aliixed our si gn atnres.
